ALBERT H. BATES, 0F GLEVELtlIiBIGiE-TS, @lilith Application filed ifarch 27, 1916., Serial No. 88,89?.

'To all `whom t 'may concern Be it known that l, ALBERT H. BATES, a citizen of the United States, residing at Cleveland Heights, in the county of Cuyahoga and State ot Ohio, have invented a certain new' and useful Improvement in Road-Maps, of which the following is a full, clear, and exact' description, reference being had to the accompanying drawings.

'lhis invention relates to road maps intended primarily for the use of automobilists, motor cyclists, etc., and the object is to provide map 'which will show at a glance not only the different routes,but 'the distance between any two points on a selected route. l accomplish this object by providing on the map route lines following the general course which the route indica ted fol lows, and l divide such lines into successive portionshaving a diierent appearance, each portion representing the same definite number of miles. The designations may consist of ditierent forms of the' same color or dit- 'erent colors,`and the subdivisions may coni'eniently be made every twenty miles, for example. Each subdivision.represents the true mileage et the route, though it i'requently happens` that the small bends, twists and detour-s of a road, which greatly lengthen its real mileage, are not apparent on any map covering any large amount of territory. Accordingly, with my map, though the successively dii'lerent portions of the route line each indicate the same mileage, they will frequently appear as diiierent lengths on the map. v With such a map as described, the automobilist can see at a glance approximately the distance between any two points. Knowing his own location at any time he can form an approximate estimate as to the time when he may expect to reach any other point -on the map simply by a glance at the 1nap,f and without measuring by any scale of miles or referring to any description.

The drawing illustrates a map made in accordance with my invention, wherein there,`4

are various route lines, each subdivided into portions having successively different `appearance and representing the same number of miles. I find it very convenient to use twenty miles as the unit, and this isfapproximately the scale shown in the drawing. As the ordinary touring speed of an automobilist is approximately twenty miles an hour, the twenty mile subdivision corre spends approximately to `an hour subdivi sion, and thus the automobilist can read his route d1rectly 1n hours without computation. ln the drawing some of the route lines are shown as alternately solid black and parallel I Each unit in the specific map shown is in-y tended to represent approximately twenty miles. lt will be noticed that b tween Rochestei" and Syracuse, for example, the unit is considerably longen in appearance than in the vicinity of Dansville. 'This indicates to the automobilist that the roads are iull oi bends around Dansville and suggests the character of the topography he. may expect. fit the same time he is not misled by the comparative closeness of Dansville and C lanandaigua 7 on the map he would be if lhe attempted to apply a xed scale of miles to the map), and he obtains his real distance by observing the number lof alternately appearing subdivisions between the two points. lt willv thus 'oe seen that all the automobilist has to do to observe the number or" subdivisions between two points (making a mental estimate of the fractional parts ofthe subdivisions ii' necessary), to see at a glance the distance and approximate time between any points. Moreover, an unusually short sub-division indicates a sinuous or detouring road with its concomitant topography.

@ne of the advantages of my map that it may be readily inspected while the car is running, when the motion interferes with reading a description. lt may also be seen in a much dimmer light than is necessary for reading a description. My map may be cheaply printed, and is very effective in furnishing the desired inforniation without requiring the user to look elsewhere than on the map itself.

Having thus described my invcnthm, what l claim is:

into successively differently appearing" portions. each portion representing the same distance.

2. A roadmap ,having designations 'of towns and lines connecting them, the lines being subdivided into successively df- 'ierently appearing portions designating the distance.

3. A road map consisting of town desig nations and lines connecting them, th'e'lines being subdivided longitudlnally into different portions of successively different appearance, each portion representing substantially lthe same actual road distance though the dimensions of the portions may vary on the map.

4. In a road map, the combination of desi gnations of towns and cities and route lines Copies of this patent may be obtained for connecting the same and following approxi v lmately the course of highways between such points, the route lines being subdivided into portions of successively different appearance, the actual -length of such; ortions on the map varying' according td the topography of the country traversed to make them indicate a substantially accurate distance on the route, whereby a shorter subdivision in- ALBERT H.
